Sure. Anything can be stacked with anything. Like Makwa asked - what are you trying to accomplish by stacking those two compounds in particular? Winny is generally confined to cutting cycles and has a significant ability to lower SHBG which will elevate free test. I think Provi is a better choice. They are both DHT derived compounds but Provi is not going to DESTROY your lipid profile while drying out your joints till they creek with pain like Winny. Those doses look like a female cutting cycle. But at 5' 10" 191 lbs. you would be an awfully big lady. The doses for a man would be much higher.
